Boston Office Tower Sells for $546 Million Discount at Auction

Why this matters

Office continues to trade in two distinct markets: trophy assets in walkable submarkets that are leasing at or near record rents, and commodity Class B and C buildings where the basis is still resetting. Underwriting on the latter has moved toward replacement-cost-minus, with credit underwriting now leaning on tenant covenant and remaining lease term rather than mark-to-market expectations. Boston life sciences absorption has moderated from its 2021-2022 pace, and the market is working through a meaningful Cambridge sublease overhang. Multifamily and trophy office remain durable. For LP-positioned capital, the read-through is that the bifurcation is now a structural feature of the sector, not a cycle to wait out.
